Material invoices

Typical? No. I have always relied on the general contractor to compile cost information. They have to track it anyway and it just seems odd to ask an architect/LEED administrator to sort through subcontractor invoices.

Acceptable? I don't see why not. It just makes it your task to convert the percentages into actual dollars so the material calculator can be filled out.

Another thought - I'm having a hard time picturing what these percentage invoices look like but it seems like it could bring you some grief if you are pursuing MRc7 Certified Wood. You do have to upload line item invoices with dollar values for that credit.

Greetings from Greenbuild Nation in Philadelphia – hence my delay in responding. I’m surprised the GC is not doing the work you are describing. You need an actual material cost for the materials themselves but maybe you can back that out from what they are providing.
